someone walks in and gives you THAT look, and you just KNOW what happens next is gonna be indescribably indescribable?

Yeah....

You know that look you get from some girls, that narrowed eyed glare that says "I will have your testicles in a jar if you step outta line here"?

Yeah....

You know that look you give a girl that says "Uhhuh...I am so sca-wed of you" and their eyes squint even further, as if they look at you hard enough through small enough apertures their unspoken threat will take hold?
